 # Completed Steps
 
+- 2026-11-02: like a failed WHOIS lookup, a lookup skipped because its RIR is
+  paused makes the fetcher wait longer before the next lookup. The longest wait
+  is one minute. The status page does not count a skip as a failure. A skip used
+  to leave the wait as it was. Each lookup asks IANA before it finds its RIR
+  paused. So while most stale ASes belonged to a paused RIR, the fetcher could
+  ask IANA every second (closes #222)
 - 2026-11-02: a peer's session going down no longer stops the prefix handler.
   The handler runs the table's `PeerDown` on a separate goroutine, one peer at a
   time, and goes on taking messages. `PeerDown` holds the table's lock for
